yTUB BOTTOM.

Application filed December 22, 1921.

To all w 7mm t may concer/n Be it known that I, Lan H. PAYNE, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful mprovements in Tub Bottoms, of which the following` is a specification.

This invention relates to tubs or other containers having their side walls composed of staves and their bottoms inserted in the end and held in place by a chime joint, and particularly to an improved construction of bottom in such receptacles.

One object of the invention is to adapt the bottom to relieve the individual staves of destructive shocks which, in known constructions of tubs or the like, are imposed by dropping the tub upon its bottom; and accordingly, one feature consists in constructing the inserted bottom with a vertical dimension that will cause it to protrude sufficiently beyond the plane of the lower ends of the staves to prevent the staves from striking a surface upon which the tub is dropped, and at the same time shall distribute the shock through the chime joint, among the staves in a manner to reduce to a minimum the shock on any individual stave and prevent tendency to displace one stave endwise with relation. to the others.

Another object is to so construct the chime joint as to materially increase the vertical dimension of the ledge which lends upward support to the bottom, and thereby greatly reduce the tendency of splitting.

In order that the invention may be fully understood, the preferred embodiment thereof is illustrated in the accompanying drawing, which shows in vertical axial section a tub embodying,` the several features thereof.

l represents the staves which, except at the chime, will be constructed and assembled through the medium of hoops or bands 2, 3, in the usual way. t represents the bottom of the tub which is introduced between the lower ends of the staves through means of a chime joint as has heretofore been the practice, but the joint between the bottom and the staves and the dimension of the bottom and the consequent relation of its lower surface to the ends of the staves are different in the present construction.

Serial No. 524,067.

The chime oint involves the recess formed by the horizontal wall 5 which sustains the bottom against upward thrust, and the downwardly and inwardly inclined surface 6 which forms a joint that tightens under the internal load of the tub; but instead of eX- tending from the inner extremity of wall 5 to the lower inner edge 7 of the circular wall provided by the staves, the surface 6 terminates at the annulus 8 and leaves a surface 7, 8 at a substantially different angle (in the present instance vertical) for centering the bottom and greatly increasing the shearing resistance of the under supporting` ledge of the chime, and renders the bottom joint very much more durable under the stresses which it must encounter in use.

The vertical dimension or thickness of the bottom a is sufliciently greater than the distance between, the wall 5 and the joint 7 to develop a substantial prominence of the bottom L beyond the lower ends of the staves,

such, for instance, as that represented by the vertical distance between the joints 7 and 9. Preferably the bottom is chamfered between the joints 7 and 9 to reduce tendency to chip the bottom.

lith the construction as described, when a tub is dropped upon its lower end, which' frequently happens in use, as for instance when removing a packed ice cream freezer from a vehicle, or dragging the same off an upper level and permitting it to drop upon a lower level, the load will be imposed upon the bottom t as a whole, or upon a sufficient portion thereof to distribute the stress over all or a sufficient number of the staves l to avoid doing violence to the structure or position of any one stave, and the durability of the tub will be greatly enhanced.

I claim:

l. A receptacle comprising side walls composed of staves, and a bottom inserted in the end of the receptacle, united with the staves through the medium of a chime joint and having a vertical dimension which presents the upper surface of the bottom a substantial distance below the lower ends of the staves and causes the bottom to support the receptacle with the staves out of contact with the surface upon which the receptacle stands.

2. In a receptacle, side walls constructed of staves, and an inverted bottom connected with said side Walls through the medium of face a substantial distance below the lower a chime joint comprising a recess terminatends of the s'taves, which causes the bottom ing a substantial distance above the lower to prevent contact of the staves With the sur- 10 ends of the staves and a vertically extending face upon Which the receptacle stands.

inner stave surface embracing said bottom Signed at Milwaukee, Wisconsin, this 14th below said recess; said bottom having a verday of Dec., 1921.
